Title:
  [Lenovo ThinkPad R61i (7650)] Fan not speeding up on high temperatures

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm using a Lenovo R61i (type 7650D6G), with Ubuntu 14.04 and up-to-date BIOS. The fan speed is well controlled on low temperatures, i.e. around/below 50°C, staying between 0 and 3000RPM. The problem is that under a higher load my cores can reach higher temperatures, like 75-80°C, without the fan being speeded up over 3000RPM. Since lmsensors shows 85°C as critic temperature for my cores (Intel Core Duo T5450), I find this quite dangerous.
  I have experienced this copying files between two hard disks, being both cores running at 50% for two hours.
